HEM500 HEM — European Wide Flange Beam (Heavy) Section Properties

HEM500 is a European HEM (Wide Flange Beam (Heavy)) per EN 10365 (successor to DIN 1025 / EN 10034) hot-rolled structural steel section. Standard European HEM dimensions per EN 10365. Verify against ArcelorMittal / Tata Steel section catalog.

Section Profile Summary

This is a standard hot-rolled I-section profile covered by EN 1993. The tabulated section properties are computed from the nominal dimensions per the governing material standard. With Ix = 159,009 cm⁴, the strong-axis flexural stiffness is suitable for preliminary sizing of beams and beam-columns.

At 524 mm deep and 270 kg/m, this is a heavy section for primary framing — transfer beams, long-span roof girders, and major bridge stringers.

Key Design Checks (EN 1993)

Design Notes

• Compactness: Verify flange and web slenderness against EN 1993 Table B4.1 classification limits for the governing load case (pure compression, pure flexure, or combined).
• Combined loading: For members under simultaneous axial force and bending, use the interaction equations in EN 1993 Section H. The governing equation depends on the ratio of required to available axial strength.
• Connection limit states: Check bolt bearing, tear-out, block shear, and weld strength at all connections. The governing connection limit state often controls the member size selection.

Verification (EN 1993): All designs using this section must be verified by a licensed Professional Engineer. Before finalizing member selection, check beam-column interaction (P-M), lateral-torsional buckling, serviceability deflections, and all connection limit states. See Engineering Disclaimer.

Worked Example: Office floor beam — hem500

Scenario: Commercial office floor — typical open-plan layout with raised floor. Simply supported I-section, 9.4 m span, 2.4 m tributary width. Service loads: 4.0 kPa dead + 3.0 kPa live (16.8 kN/m total).

Given:

• Span L = 9432 mm (9.4 m)
• Total service load w = 16.8 kN/m
• Live load portion w_L = 7.2 kN/m
• Section hem500: Ix = 1590.1 × 10⁶ mm⁴, Sx = 6,069,000 mm³, Zx = 6,959,000 mm³
• Steel: fy = 355 MPa, E = 210,000 MPa
• Design moment resistance: φMn = 0.9 × Zx × fy = 2,470 kN·m

Step 1 — Live load deflection:

Δ_LL = 5 w_L L⁴ / (384 E Ix)

Δ_LL = 5 × 7.2 × (9432)⁴ / (384 × 210000 × 1,590,090,000)

Δ_LL = 2.2 mm

Step 2 — Deflection limit (L/300):

Δ_limit = L / 300 = 9432 / 300 = 31.4 mm

Step 3 — Dead + live deflection:

Δ_total = 5.2 mm

Step 4 — Design check:

✓ Live load deflection is within the L/300 limit.

Verify the design moment M*_Ed (from factored loads 1.35G + 1.5Q per EN 1993) does not exceed φMn = 2,470 kN·m. Also confirm shear resistance and bearing details at the supports.
